Using the building site of the Paris Philharmonie as their source location and inspiration, the trio of Pascal Battus using found objects, Bertrand Gauget on saxophone, and Eric La Casa on microphones, improvise and record the background sounds, machines, and environmental influences, using those recordings to create these three fascinating compositions.

Three improvisers, Pascal Battus (rotating surfaces, found objects), Bertrand Gauguet (saxophones) and Eric La Casa (microphones) recorded while playing at a working building site in Paris and also in studio.
